General Information

Term

adult ellipsoid body ring neuron R4d

ID (Ontology)

FBbt:00007538 (Fly Anatomy)

Definition

Ring neuron R4 whose arborization in the ellipsoid body is largely restricted to the outermost part of the ellipsoid body outer central domain (Renn et al., 1999; Omoto et al., 2018). It has glomerular dendrites restricted to the lateral part of the superior bulb (Omoto et al., 2018). In the ellipsoid body, it synapses to E-PG neurons, as well as forming inhibitory connections with other R4d neurons (Turner-Evans et al., 2020). It is GABAergic (Turner-Evans et al., 2020).[ FlyBase:FBrf0111476 FlyBase:FBrf0210154 FlyBase:FBrf0240929 FlyBase:FBrf0246945 ]
